Low dimensional graphite has recently attracted much attention. We have developed a new carbon preparation method "Template Cabdonization" which utilizes the interplanar spacing of montmorillonite for the preparation of 2-dimensional graphite. The aim of the present project is to produce carbon materials from this unique carbon. In the first year, we tried to synthesize K-GIC (potassium-graphite intercalation compound), and in the second year the application to the secondary battery was attempted. Some other clays were used for the purpose of clarifying the effect of the structure of host materials.1. The extent of crystallite breakage was quite small in the process of interalation and desorption for the case of low dimensional graphite.2. The lithium secondary battery derived from this carbon showed excellent behaviors in the stability and charge density.3. Taeniolite, which is highly crystalline clay, produced the carbon with high orientation and high crystallinity.4. On the other hand, saponite produced a very unique carbon which swells upon the contact with organic liguids.5. Magnetoresistance of the graphite from montmorillonite was determined. The value was much smaller than expected from the X-ray parameter. This suggests the low dimensional nature of this carbon.

低维石墨最近引起了人们的广泛关注。我们开发了一种新的碳制备方法“模板化”，该方法利用蒙脱石的晶面间距来制备二维石墨。本项目的目标是用这种独特的碳生产碳材料。第一年尝试合成K-GIC（钾石墨插层化合物），第二年尝试在二次电池中的应用。为了阐明基质材料结构的影响，还使用了一些其他粘土。 1．对于低维石墨来说，在嵌入和解吸过程中微晶破裂的程度相当小。 2．由该碳制成的锂二次电池在稳定性和充电密度方面表现出优异的性能。 3．带云石是一种高结晶粘土，所产生的碳具有高取向性和高结晶度。 4．另一方面，皂石产生一种非常独特的碳，它在与有机液体接触时会膨胀。5．测定了蒙脱石石墨的磁阻。该值远小于 X 射线参数的预期值。这表明这种碳的低维性质。
